IMPROVEMENT IN MACHINES FOR MAKING HORSE SHOE-NAILS.

Specification forming part of Letters Patent No. 42,709, dated May 10, 1864.

To all whom it may concern:

Be it known that we, JAMES WHITE, of Cleveland, in the county of Guyahoga and State of Ohio, and JOHN MADDEN, of Young'stown, in the county of Mahoning and State of Ohio, have invented new and useful Improvements in Machines for Making Horseshoe- Nails and we do hereby declare that the following is a full and complete description of the construction and operation of the same, reference being had to the accompanying drawings, making part of this specification, in which- .Figure 1 is a top view. Fig. 2 is an end view. Fig. 3 is a side view, and Figs. 4 and 5 are detached sections.

. Like letters of reference denote the same parts in the several views.

Our improvement relates to certain devices, their arrangement and operation, for making horseshoe-nails, whereby a blank is cut 011' from the rod, the head formed, and the nail drawn out into the proper form and size.

I In the several figures, A represents the frame of the machine.

- B is a wheel, its shaft being supported by the frame in bearings, and operated by the driving-wheel G.

In the upper part of the machine, in a line with the top of the wheel B, there is a table, D, to the middle of which is secured the guide E,. having a slot, E, in which the rod of nailiron is placed as it is passed into the machine. In .this guide the blanks are cut 0E. by the cutter F and the head formed on the next nail. The cutter F stands in a vertical position, the cutting-edge extending below the main body, the lower end, immediately behind the cutting-edge, being so formed, as seen at F in Fig. 5, as to give the proper shape to the head of the succeeding blank by its pressure upon the heated nailrod, by pressing the same into a sort of matrix in the guide E, presently to be described. This is done by a slight excavation in the sides of the slot E. The cutter-head is secured to the arm F, which arm extends in a horizontal direction from the rock-shaft to which it is attached. The rock-shaft G is operated by means of a curved arm, H, which is attached thereto, the arm being brought into contact with a pin, I, projecting from the side of the wheel B, as the wheel B rotates in the direction of the arrow.

To the rock-shafts M N, connected to the frame A by pivots seen at m n in Fig. 3 are secured arms M and N, that extend nearly to the circumference of the wheel B. These arms M N widen out into curved faces m n, with projections or spurs m n, as represented in Fig. 3.

O P and S T represent similar arms, connected, by means of rock-shafts, to the vertical sides of the frame of the machine. Both the arms M and N, O P, and S T are pressed forward by a spring. 2', placed behind them, and thus, when not in action upon the forming-nail, are thrown forward to the position shown in Fig. 3. A lip or catch, b, projects from the circumference of the Wheel B, shown in enlarged Fig. 4., the office of which is to seize and hold the head of the nail-blank while being formed. The bar a, which connects with the lip 12, extends into the body of the wheel B,

as shown in section, Fig. 4. The inner end is' surrounded by a coiled spring, Z, the action of which is to keep the catch extended beyond the face of the wheel B to a distance suflicient to allow the head of the blank from which the nail is made to pass freely under it, in order that it may be seized by the catch. The arm a is surrounded by a sleeve, f, which projects from the face of the wheel a distance sufficient to prevent the nail-blank from resting immediately upon the face of the wheel. This sleeve is surrounded by a steel plate, B, which forms the surface upon which the nail is formed.

At L, in Fig. 4, is seen a nut, against the under side of which the spring Z rests, the nut being secured to the arm a. The arm a, with the lip b, is drawn inward by means of the cam c, which is placed about in themiddle of the rod to. The cam is operated by means of the arms U and V, which extend outward upon each side of the Wheel B. As the wheel B rotates, the arm V is brought into contact with a projection, Y, on the inside of the frame A, which draws in the rod to, causing the lip b to seize hold of the head of the nail-blank that is at the instant interposed between the lip and the face of the wheel in the manner hereinafter stated. The inner end of the sleeve f forms the stationary point against which the cam operates, while the nut L conveys the movement to the arm a. The projection X, upon the opposite side of the wheel B and attached to the frame A, serves to reverse the action of the cam by the arm U being brought into contact therewith in the rotation of the wheel. The sleeve f is so arranged that it cannot be moved out any farther from the periphery of the wheel than simply to hold up the nail from the face of the wheel B, there being a shoulder or collar, f, on the sleeve f, which strikes against the plate B, which prevents the slide from moving out farther than needed, the inner end of the sleeve forming a surface, 0, corresponding to the cam 0, as

represented. The spring Z keeps the lip 12 and sleeve fin the desired position.

In the slotted guide E is a slide, (7, Fig. 5,

' that is attached to an arm, L, which arm is secured to the rock-sh aft L, and is operatedby means of the arm It, which is secured to the rock-shaft L, and is brought into contact with the cam S, whose position is indicated by the dotted lines on the oppositeside of the wheel B from which it is placed. Behind the slide d is placed the spring R, which is compressed by the action of the cam S upon the arm R, and so soon as the cam S, by the movement of the wheel B, passes from the arm R, the spring suddenly throws the slide 01 forward, striking against the point of the nail-blank, as shown at d in Fig. 5, and throws it forward under the lip 11, so that the lip fastens upon the head and holds it fast.

I The manner of making horseshoe-nails with this machine is as follows 2 The rod of nail-iron is fed into the machine in a heated state at E, Fig. 5, of. the guide E, as shown by the red line under the center of the head F. By turning the driving-wheel the pin 1 is brought to bear against the curved arm H, which forces down the cutterhead, as shown in Fig. 3, cutting off the nail-iron and forming a head on the end of the bar for the next succeeding nail. The spiral spring H, attached to the arm H, causes the cutter-head to ascend when the pressure of the pin is removed from the arm, as indicated by the dotted lines H in Fig. 3. The slidednow comes into action, it being so arran ged that as soon as the blank is cut off and the head formed for the next nail the arm It comes in contact with the cam S on the side of the wheel B, and the slide is moved back, as indicated by the dotted lines 01, and the blank, with itshead ready formed, falls to its position in Fig. 5. As soon as the arm R passes off the cam and the pressureis removed, the spiral spring S forces the slide back, which throws the blank forward into the lip b on the circumference of the wheel B, and between the vibrating arms 0 and P, which are pivoted to the frame A at right angles to the wheel B. Instantly after the head of the nail is passed under the lip I) the arm V is acted upon by the projection or lug Y as to turn the cam, thereby causing the lip to fasten down upon the head of the nail until released by the reaction of the lug X on the arm U of the cam. The arms 0 I? have projections 0 p on the ends, against which the lip b comes, and, as it is passing between them with the blank for the nail, the arms are forced back, as indicated by the dotted lines o p, bringing the curved edges or face against the sides of the nail, thereby drawing out the iron. When the nail is drawn through between the arms by the turning of the wheel B, the springs t" cause the arms 0 P to take their former position, ready for further action on the succeeding nail-blanks as they are fed into the machine. The sleeve f, around the arm a of the lip 11, is elevated a little above the surface of the wheel, as before stated, the object of which .is to raise the blank nail above the surface of the wheel, so that it can be pressed upon the sides of the vibrating arms 0 P and S T with out producing feathered or rough edges on the under side, as it otherwise would if the press ure were down upon the face of the wheel. The sleeve, by the action of the spring, keeps the blank up after it has been pressed down by the vibrating arms M N. The nail is carried around with the wheel B, under the arms M N, that are suspended on rock-shafts in a line with the wheel, and the lip b, coming in contact with the projections m n, draws back the arms, as indicated by the dotted lines M N,causing the nail to be pressed between the periphery or face of the wheel, and the curved faces m a pressing the upper and lower edges of the nail and drawing it out. The springs t 1' cause the arms to return to their position when the nail passes from under them. The nail is also carried around while held by the lip 1) between the arms S T, which are similar to O 1, being at right an-. gles to the wheel and pressing against the sides of the nail. The nail is then carried around with the wheel until the arm U comes in contact with the lug X, which turns the cam so as to raise the lip b from the head of the nail, letting it fall perfectly formed and ready for use. The arms at right angles to the wheel that press the sides of the nail, and those in a line with the wheel and that press the upper and under side of the nail, can be placed alternately with each other, working the sides and top alternately, thus drawing out the nail into the desired shape. A numbJI of nails can be formed by one revolution of the wheel, by having a number of lips b on the circumference and a corresponding number of pins I on the sides to operate the cutter-he'ad in cutting off the nail-blank. As the rod of iron of which the nails are to be formed is fed into the machine, the cutter-head, as it descends, cuts off the blank and forms the head of a subsequent nail, and as this is moved along and the cutter-head descends again it cuts off this blank nail, forming at the same time the head of the next blank, and so on. The cutter-head performs two functions, that of cutting off the blanks and forming the heads. In Fig. 6 the form of the nail-head is shown, 0 being a front view, and e an edge view.

What we claim as our invention, and desire to secureby Letters Patent, is

1. The herein-described devices for cutting off the blank and shaping the head at one operation.

2. The herein-described devices for throwing the blank forward into the lip b in the manner specified.

3. The herein-described devices for holding the nail while it is being drawn out into shape and releasing the same.

4. The vibrating arms MNO P S T, in combination with the wheel B, operating as and for the purpose specified.
